The 65 people who might run for president in 2016

The Democratic and Republican fields contrast sharply. Hillary Clinton is the clear front-runner, while there is no front-runner on the Republican side.

Twenty-three Democrats have been mentioned as a candidate or are eyeing a bid, according to an analysis by The Hill. The GOP side has 42.

Most of the people on this list won’t run, and some have adamantly claimed that they’re not interested. But many politicians have changed their minds on seeking the White House. Before mounting his 2008 bid, then-Sen. Barack Obama (D-Ill.) said he wasn’t running.

The following is The Hill’s list of 65 people who might run for president in 2016.

Democrats

Vice President Biden — Will he or won’t he? Polls show he is trailing Hillary Clinton badly. Last month, President Obama said Biden would be a “superb” commander in chief.

California Gov. Jerry Brown

Brown has run for president three times. He says a fourth is “not in the cards.”

Montana Gov. Steve Bullock — Bullock is seen more as a vice presidential possibility.

Hillary Clinton — Will she run? Of course she will.

New York Gov. Andrew Cuomo — He would be a top contender if Clinton wasn’t running. But the ongoing corruption probe in New York looms over Cuomo’s head.

Howard Dean

The former Vermont governor and 2004 presidential candidate told CNN he hopes Clinton wins. But last year, he warned she wouldn’t get a pass in the Democratic primary.

Sen. Kirsten Gillibrand (N.Y.) — Gillibrand has made it clear she backs Clinton. But if the former first lady doesn’t run, Gillibrand might.

Al Gore — Few think he will run, but political analyst Mark Halperin sparked new speculation on “Morning Joe” last month, when he said the former vice president might challenge Clinton.

New Hampshire Gov. Maggie Hassan — She might opt to run for the Senate in 2016.

Colorado Gov. John Hickenlooper — A popular governor who has indicated he won’t run.

John Kerry

The secretary of State absolutely ruled out a 2016 campaign earlier this year. But then again, so did Barack Obama before he ran in 2008.

Sen. Amy Klobuchar (Minn.) — See Gillibrand. Klobuchar visited Iowa last year and will be back in the Hawkeye State this week to stump for Senate hopeful Rep. Bruce Braley (D-Iowa).

Sen. Joe Manchin (W.Va.) — There’s a Draft Joe Manchin effort out there, but the centrist is more likely to run for governor again should he leave the Senate.

Maryland Gov. Martin O'Malley — Uphill climb for O’Malley. How tough? Three members of the Maryland delegation (Sen. Barbara Mikulski and Reps. Steny Hoyer and John Delaney) have already said they would back Clinton in the Democratic primary.

Janet Napolitano The Washington Post last year called the former governor and Cabinet official “a woman to watch in 2016.”

Missouri Gov. Jay Nixon — The unrest in Ferguson is a huge test for Nixon, whose last name wouldn’t be an asset if he runs.

Massachusetts Gov. Deval Patrick — Will likely run for president at some point, but not in 2016.

Sen. Bernie Sanders — The liberal Sanders, who is technically an independent, has said he would challenge Clinton if no one else from the left launches a bid.

Brian Schweitzer — The former governor of Montana has had a rough summer.

Sen. Mark Warner (Va.) — Warner stunned political observers, when he didn’t run for president in 2008. He instead ran for the Senate and is up for reelection against Ed Gillespie this fall.

Sen. Kelly Ayotte (N.H.) — Ayotte, who is up for reelection in 2016, is already being discussed as a vice presidential pick.

Rep. Michele Bachmann (Minn.) — Tea Party favorite has said she might run again in 2016.

Former Mississippi Gov. Haley Barbour — Barbour is well liked by the GOP establishment and was included in a Republican National Committee straw poll in January.

Rep. Marsha Blackburn (Tenn.)

Blackburn denied a report she is mulling a bid.

John Bolton — The former U.S. ambassador to the United Nations is leaving the 2016 door open.

Scott Brown — Brown is the underdog in his race against Sen. Jeanne Shaheen (D-N.H.).

Jeb Bush — Bush fatigue would be a significant obstacle for the former Florida governor.

Herman Cain — Jon Stewart prayed on the air that Cain would run again.

Ben Carson

Carson is a rising star in the GOP.

New Jersey Gov. Chris Christie — Bridge-gate hasn’t deterred Christie, who sounds like he’s going to be a candidate.

Sen. Ted Cruz (Texas) — Tea Party star must convince kingmakers that he can beat Clinton.

Mitch Daniels — The ex-governor of Indiana decided against running in 2012 because of family concerns.

Oklahoma Gov. Mary Fallin — The former House member is in the mix of speculation.

Tennessee Gov. Bill Haslam — He says he’s not interested in running.

Newt Gingrich — The 2012 presidential candidate and ex-Speaker might run again. Asked by Fox News’s Greta van Susteren about throwing his hat in the ring, Gingrich responded, “Ask me that in January of 2015.”

Rep. Steve King (Iowa) — A kingmaker in Iowa and a hard-liner on immigration.

New Mexico Gov. Susana Martinez

The first female Hispanic governor is not expected to run for president. But she will be a leading vice presidential candidate.

Rep. Cathy McMorris Rodgers (Wash.) — She has a bright future, though a presidential run in 2016 probably isn’t in the cards.

Sarah Palin — The RNC put her in its straw poll, but most think the former Alaska governor will remain on the sidelines.

Sen. Rand Paul (Ky.) — Paul, who is up for reelection in 2016, looks like a sure bet to run for president. Of all the possible 2016 GOP hopefuls, Paul has arguably had the best 2014.

Indiana Gov. Mike Pence — Pence is a dark horse who shouldn’t be overlooked. The former House member was Tea Party before the Tea Party existed and is well respected by social and fiscal conservatives.

Texas Gov. Rick Perry

Comebacks are common in politics, but can Perry pull it off? He has two things going for him: The border crisis has put him front and center on the national stage, and the right has rallied behind him in the wake of his indictment in Texas.

Sen. Rob Portman (Ohio) — Portman, who is up for reelection in 2016, is headed to New Hampshire next week.

Condoleezza Rice — The former secretary of State routinely comes up in this conversation, but the chances of a Rice bid are remote.

Rep. Mike Rogers (Mich.) — The retiring House member and soon-to-be talk-radio host hasn’t ruled out a run.

Mitt Romney — The rumors of another Romney run continue to persist.

Sen. Marco Rubio (Fla.)

Rubio will have to decide whether to run for president or reelection in 2016. As he said, “you can’t be on the ballot for two different offices” in Florida.

Rep. Paul Ryan (Wis.) — He seems more intent on becoming Ways and Means Committee chairman than running for president.
